Problems solved by technology

However, when Internet Protocol Version 4 (Internet Protocol Version 4, referred to as "IPv4") network transmits data, the address included in the header of the data is only the source address and the destination address, which cannot be transmitted by stripping the address of each layer. Data, data transmission in IPv4 network has certain limitations

Abstract

The embodiment of the invention discloses a method and device for transmitting data. The method comprises the following steps: a first network node receives a message, wherein a message header of the message carries indicating information, the indicating information is used to indicate a target link number corresponding to each node number in N node numbers, the N node numbers correspond to N network nodes on a forwarding path of the message, and N is an integer greater than or equal to 2; the first network node determines the node number of the first network node; the first network node determines the first target link number corresponding to the node number of the first network node according to the message header of the message; and the first network node forwards the message on a link corresponding to the first target link number. Thereby, the application range of data transmission in networks can be improved.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a method and device for transmitting data in the field of communication. Background technique [0002] Multi-Protocol Label Switching (MPLS for short) technology is the next-generation Internet broadband network technology. MPLS technology separates data routing and forwarding, uses constrained routing to establish explicit paths, and then establishes label switching paths ( Label Switched Path, referred to as "LSP"), segment routing (Segment Routing, referred to as "SR") is an MPLS technology, SR mainly includes node labels and link labels, the node label is the shortest route calculated by each node to reach the target node Path information, and send the current node and next hop information to the forwarding table. Each node saves all node labels in its own forwarding table. According to the shortest path information and node labels, it can finally reach the target node. T...
